克拉霉素耐药和女性影响慢性胃炎幽门螺杆菌根除的失败
Abstract摘要
Background:
Theeradicationrateofthefirst-linetripletherapy(aprotonpumpinhibitor,clarithromycin,andamoxicillin)forHelicobacterpyloriinfectionhasgraduallydecreasedinKorea.Weevaluatedwhetherclinicalparameters,clarithromycinresistance,andCYP2C19genotypecanaffecttheeradicationfailure.
背景:
在韩国,一线三联疗法(质子泵抑制剂、克拉霉素和阿莫西林)治疗幽门螺杆菌感染的根除率逐渐下降。我们评估了临床特征、克拉霉素耐药性和CYP2C19基因型是否是根除失败的影响因素。
Methods:

方法:
共有例幽门螺杆菌阳性慢性胃炎患者被纳入研究,接受7天克拉霉素三联疗法。通过检测幽门螺杆菌23srRNA中AG和AG点突变进行克拉霉素耐药试验。采用限制性片段长度多态性聚合酶链反应检测CYP2C19基因型第5外显子GA和第4外显子GA的多态性。治疗4周后通过13C尿素呼气试验评估根除情况。
